DICE has just released patch R4 for Battlefield 4 Ranked Servers.
We have started a massive roll-out to all servers, as we speak.
Change Log:
*Fixed the fairfight rcon commands crashing the server when used on the command line or in the startup.txt.
*Re-added the vars.unlockMode setting.
*Fix for reloading of full mags in normal games (this is hardcore setting that should now no longer be used as a default when running a non-hardcore game)
*Various crash fixes.
